Who is the Japanese rush?

The Acorus Gramineus is a very beautiful plant and very decorative. In addition to that, it's a multifunction plant! It can be used in freshwater aquariums, terrariums, paludariums and pond areas (generally, in all very wet soils).

However, it should be noted that it likes much more to be in a semi-submerged situation. This is why it will be particularly adapted to paludariums and ponds. Conversely, in a completely submerged situation, it will not survive long.

These beautiful and long leaves are quite hard. Because of this, this plant is very resistant.

In aquarium, it can be placed in a tray with vegetarian cichlids without risk.

Planting and maintenance

How to plant and maintain the Japanese rush?

Given its height, it should be reserved for aquariums and other containers high enough, or in open containers. It is also necessary to provide a good height of substrate to satisfy the rooting rhizomes (count at least 10 cm or 4 inches). Maintenance of this species will require Co2 input in almost all submerged situations.

The Acorus Gramineus will tend to want to emerge out of the aquarium because that is how it is in its natural state (if it remains fully submerged, it will live less time). This is also how you can hope to make it bloom: partly submerged and partly emerged. It flowers then discreetly, usually in June and July. Its flowers are slightly yellow, white or green.

For the basin, the rhizomes of the Acorus stabilize the bank by retaining the earth effectively. You can plant it from March to November in the ground (at least 10 cm deep or 4 inches). Note that this plant does not withstand temperatures below 0°C or 32°F and hot weather.

Farming

How to farm the Japanese rush?

Farming occurs by division of the rhizomes, to be done in the spring or fall.

To multiply it, let it grow in containers containing soil and 10 to 20 mm or 0.4 to 0.8 inches of water. A long rhizome will form in 1 or 2 years. Clean it, wash it and let it float in the aquarium or in the pond (in summer). New plants will start to grow from the rhizome after 10 to 30 days. When the leaves are 25 cm or 10 inches long, separate the rhizome and plant the leafy cuttings.
